LOS ALAMOS NEW MEXICO (Reuters) - It's official. Soccer has been the most exciting sport for the last 100 years but baseball is catching up.

A team of scientists from the Los Alamos National Laboratory in New Mexico studied a string of sports to discover which offered the most unpredictable and surprising results -- and soccer was the winner.

"If there are no upsets then every game is predictable and hence boring Eli Ben-Naim told New Scientist magazine.

He and team members Sidney Redner and Federico Vazquez analyzed results from more than 300000 games over the last century from the U.S. national hockey football basketball and baseball leagues and the top English soccer league.

Their results showed that the "upset frequency" was highest for soccer followed by baseball hockey basketball and finally American football.

But there was a twist in the tale for soccer fans.

When the team studied data from just the last 10 years English soccer and American baseball swapped places suggesting that soccer had become more predictable over the past decade.
